This invention has to do with the provision of a new gasket for use with spools or bobbins used in the wet-treatment of freshly spun artificial laments.

5 More especially, my invention comprises a gasket arrangement whereby a plurality of spools or bobbins may be hermetically sealed together in order that neither gas nor liquid may pass to the interior of the spools, etc., except through the regulation openings.

One object of my invention is to provide a simple yet effective means for uniting a plurality of spools used in the wet-treatment of artificial filaments.

In the manufacture of articial filaments, especially by the viscose process, the filaments are spun into a bath, and then wound upon foraminated bobbins in order that they might be treated with liquids under the action of either vacuum or pressure. The foraminated or perforated bobbins are arranged in tiers in a washing tank, and the liquids used in washing, desulphurizing, bleaching, etc., passed through the body of the wound yarn and through the holes into the spool or bobbin.

When two or more of these spools or bobbins are arranged one above the other, it is necessary to provide some means so that the plurality of spools or bobbins may be washed. etc., as one, and so that there is no way in which the liquid may pass except through the yarn body itself.

Such an arrangement is disclosed in the fol- V lowing description, and in the accompanying drawing, in which:

Figure 1 is an elevational view, partly in cross section, showing the gasket arrangement before the gasket is set therein; A

Figure 1a is a plan View of Figure 1;

Figure 2 is a cross sectional View of the gasket; Figure 2a is va plan View of the gasket;

Figure 3 is a cross-sectional view of a modied form of gasket; and

Figure 4 is a plan view partly in cross section of the complete gasket in place between two spools or bobbins.

- In order to caulk two bobbins or spools any type or kind of rubber may be used. In operation 50 the rubber is sucked against the spools, and the connection therebetween is thereby 'made airtight.

However, if the gasket is made of pure rubber,

and warm liquids are used, the liquids tend to swell and deform the rubber, and the spools D5 thereby are made to seat improperly. In the present device, however, all of these disadvantages are done away with.

The portion 1 shown in the accompanying drawing is made of some resistant material, such as hard rubber, bakelite, stainless steel, glass, stone, etc., and is shaped so that it will seat the bobbins or spools to be associated therewith. A cylindrical shap'e has been found best suited for this purpose. The top portion 3 of the ring l should be tapered so that the liquids may be 60 properly drained and so that no liquids will tend to stand between the rims of the bobbin and the center portion of the ring arrangement. A groove 4 is formed about the middle of the ring 1 and it is into this groove that the gasket 2 is placed. 70 This gasket should be so shaped that it will not easily be withdrawn from the groove. This portion 2 is made of any soft rubber. As shown in Figure 4, two bobbins 5 upon which a yarn body is wound, are placed so that the lower part of the upper one and the upper part of the lower bobbin 6, 6 are pressed against the soft rubber. When pressure or suction commences the ow of liquids through the yarn body, the two bobbins tend to come closer together, and thereby help to seal the connection between them.

As illustrated in Figures 1 and la crosswise drainage grooves 9 are shown. These grooves 9 are shown as slanting inwardly towards the center of the gasket l. The soft rubber insert 2 also has grooves l0 which coincide with the grooves 9 when the insert 2 is in position in the groove 4 of the portion l so that a perfect drainage is insured from the crevice formed by the tapered edges of the gasket 1 in conjunction with the spool 5 during the treating operations. This is brought out in Figure 4 of the drawing where it will be seen that grooves 9 and l0 form to make one drainage groove when in operation.

In Figure 3 there is shown a modified form of gasket which may be used, and comprises a rubber ring 7, of such a thickness as to snugly iit within the groove 4. The outer periphery of the gasket is rounded as shown at 8.

In operation, the hard rubber or other type of ring is provided, and the soft rubber gasket placed in the groove therein. The bottom bobbin is suitably secured to the base of the washing tank, and this ring and gasket placed thereon. A second bobbin is then placed on top of the rst, and the succeeding bobbins also set in place. When vacuum, for example is applied, the liquids in the tank pass through and treat the yarn body on the spools or bobbins, and then pass through the center of the bobbins. Such a caulking arrangement as I have devised serves to simplify the seal between the bobbins, and to prevent the passage of any liquid or air anywhere except through the perforations or foraminations provided in the bobbins.

Having now described one modification of my invention, I wish it understood that I do not thereby limit the scope of my inventionotherwise than is indicated in the appended claims.

What I claim is:

1. A gasket comprising a hard, resistant ring having inwardly tapered edges, a groove about the peripheral edge of the ring, and an insert of relatively soft material extending beyond the edge of said ring, the said inner resistant ring be- RICHARD GOLLONG.
